President Barack Obama has some degree of facial asymmetry. In this momentary and relatively neutral emotional moment, we can see that the nasal-labial furrow (which runs from the side of the nose down to the corners of the mouth) is more shallow on Barack's right side - however it runs down past his mouth corner. On his left - it is more deeply defined but stops at the corner of the mouth. This asymmetry (among other things) makes some nonverbal signals more difficult to interpret. One example of this phenomenon is that - to many Mr. Obama will seem as if he is feeling contempt when he is not. Below however are examples of two very subtle and very real microexpressions of contempt.
During the 0:14 second mark in his speech yesterday at The Hague, just prior to and just after "... Russia's ..." (during 0:19 shown in image below) when President Obama says, "..... With respect to Mr. Romney's ah, assertion that, ah ... Russia's, ah, number, our number one, geo-political foe ... " (highlighted with red).
Note that at both of these moments, the presidents eyelids are closed in a slightly extended blink.
This extended blink in this context serves as a "Contempt-Amplifier" - which is extremely valuable yet very under-appreciated body language signal.
There are multitudes of additional nonverbal examples seen in this short video. How many did you miss?
